Since 2024, B1 is the minimum language level required for German naturalization (Einbürgerung). This guide explains exactly what is required, which certificates Germany accepts, and gives you a complete free preparation path.
The Staatsangehörigkeitsgesetz (StAG) — Germany's citizenship law — was updated in 2024. Under §10 StAG, a key requirement for naturalization is:
"über ausreichende Kenntnisse der deutschen Sprache verfügen" — possess sufficient knowledge of the German language at level B1 of the Common European Framework of Reference for Languages (CEFR).
B1 is also required for Niederlassungserlaubnis (permanent residence permit) after 5 years. Some applications require higher levels — check with your Ausländerbehörde.

Start B1 preparation here →The Goethe B1 and telc B1 both test four skills. Here is what each section requires and why it matters for citizenship:
Read articles, emails, announcements, and short texts. At B1, these include: newspaper articles, official announcements, job advertisements, and personal letters. For citizenship life: understanding official letters from Ämter, reading rental contracts, understanding public notices.
Listen to radio news, conversations, short interviews. At B1: understanding main points and specific details. For citizenship life: phone conversations with authorities, understanding neighbors and colleagues, TV news comprehension.
Write a formal email (~80 words) and an opinion text (~80 words). For citizenship life: writing to the Finanzamt, Krankenkasse, or employer. Formal German communication.
Introduce yourself, present a topic from a card, negotiate/discuss with another candidate. For citizenship life: the naturalization interview itself requires B1 speaking ability.
